Michell Instruments QMA601 process moisture analyser

Michell Instruments’ QMA601 process moisture analyser is designed for retrofitting into existing systems, enabling older plants to access developments in quartz crystal microbalance technology for trace moisture measurements.

The product can be installed as a self-contained analyser or sampling system package within hazardous areas (IEC Zone 1 or 2, NEC Class I, Division 1 or 2) and is equipped with two analog outputs that are configurable for either current or voltage scaling. It is available powered with either AC or DC, while Modbus RTU protocol over RS485 is also provided to connect to a SCADA or similar data acquisition device.

The product also features an intuitive, colour, touch-screen interface that enables users to monitor, log and configure the analyser in the hazardous zone without the need for a hot-works permit, or any disruption to the process. Operation from a control room is also possible with remote application software.

The analyser is fully certified for use in hazardous areas (ATEX, IECEx and CCSAUS). Typical applications for the product are those that require precise measurements of trace moisture in hazardous areas, such as glycol dehydration of natural gas, natural gas transmission and storage and dehydration of alkenes feeding polymer production.
